SWIVEL-LOOM.

SPECIFICATION forming part of Letters Patent N o. 467,262, dated January19, 1892.

Application filed June 24, 1891.

To all whom it may concern:

Be it known that I, WILLIAM J. LUTTON, of Paterson, in the county ofPassiac and State of New Jersey, have invented a new and usefulImprovement in Swivel-Looms, of which the following is a specification.

My invention relates to an improvement in swivel-looms, in whichprovision is made for operating the swivel-shuttles at the moment thevibrating lever which communicates rnotion to theswiVel-shuttle-operating mechanism carried by theswivel-shuttle-supporting beam reaches either end of its stroke.

The improvement is particularly adapted to use in connection with loomsof the dropbox type, in which the swivel-shuttle beam is allowed to fallto bring the swivel-shuttles into position for use at the same time thatthe drop-boxes are lowered to throw the shuttles therein out of use, andis an improvement upon the general structure shown and described in mypatent, No. 460,477, granted September 28, 1891.

A practical embodiment of myinvention is represented in the accompanyingdrawings, in which- Figure 1 is a view ofthe loom in front elevation,partly in section. Fig. 2 is a partial plan view ot' theswivel-shuttle-actuating mechanism and its connection with the mainshaft.. Fig. 3 is a view of the same in side elevation, partly insection. Figs. et, 5, and 6 are views in side elevation, partly insection, showing thethree positions whichthe vibrating operating-levermay assume with respect to the parts intended to be operated thereby.Fig. '7 is a partial horizontal section through the swivel-shuttle beam,taken on line a: of Fig. 13. Fig. 8 is a similar view taken on line y yof Fig. 13. Fig.`9 is asimilar view taken on line ,a .z of Fig. 13. Fig.10 is a partial vertical longitudinal section of the swivelshuttle beam.Fig. 11 is a transverse section through the swivel-shuttle beam, takenon line w w ot Fig. 10.

carrying a drive-pulley d2, to which power is l applied from anysuitable source.

The mechanism carried by the swivel-shuttle beam for imparting motiondirectly to the swivel-shuttles is connected With the actuatingmechanism supported in the loom -frame and under the control ot' thedropping of the shuttle-boxes to throw it into and out of connectionwith the drive-shaft D by a lever E, pivotally secured to one of thelay-swords at e and having its upper end connected with the mechanismcarried by the swivel-shuttle beam and its lower end engaged with theactuating mechanism driven by shaft D.

My invention contemplates the prompt swinging of the lever E, no .matterat which end of its stroke it be when the shuttle-boxes drop, and themovement of the swivel-shuttles in the right direction, no matter atwhich end of their strokes they may have been left.

The shaft D has ixed thereon a wheel F,

provid ed with pins or studs f, projecting laterallytherefromatintervalsalongitsmargin. In the present instance four such pins areshown at equal'distances apart, adapted to engage the radial slots f ina wheel Fof the crossof-honor type and thereby impart to the said wheelF and to the shaft f2, on which it is fixed, a continuous variablerotary movement. The shaft f2 has fixed thereon a cam-wheel G, providedwith a cam-groovegin its periphery adapted to receive the stud g on thelaterallyvibrating lever G', the latter being pivotally secured at oneend, as at g2, to a cross-piece a2, and its free end reaching forwardlyand resting on the surface of an enlarged portion 7L of a longitudinallysliding and rocking shaft H, mounted in suitable bearings in the frameA. The shaft H is provided with a loop h adapted to receive the lowerend of the lever E hereinbefore referred to, and to cause it to vibratetogether with the longi tudinal movement of the shaft H, and at the sametime permit said shaft to rock without disturbing its connection withthe lever. The enlarged portion h of said shaft H is pro- IOO videdwit-h a pocket h2, adapted to receive the free end of the vibratinglever G' when the latter is at one limit of its stroke at the time theshaft II is rocked, and thereby form a' connection between the saidshaft Il and vibrating lever G to cause the said shaft Il to be slidlongitudinally by the vibratory movement of thelever. The shaft I-I isalso provided with a crank h3, connected by a rod h4 with the drop-boxframe, so that as the dropboxes fall the shaft H will be rocked. lf thenit happens that the vibrating lever G be at the limitof its stroke tocorrespond with the pocket h2 in the enlarged portion h of the shaft IIat the moment the drop-boxes fall, there will be a prompt engagement ofthe lever G' with the shaft II by the entrance of its end into thepocket h2, so that the said shaft, and hence the lever E and hence theswivel-shuttle mechanism connected with the lever E, will be promptlyactuated. Such a position of the parts is represented in Figs. l and 2.If, however, it shall happen that the drop-boxes fall when the vibratinglever G is at the opposite end of its stroke, the rocking of the arm Hwould no longer engage the end of the lever G' within the pocket h2. Inorder, however, to secure an engagement with the lever G, which shallstill slide the shaft II in the same direction as it would have beenslid had the lever G' engaged therewith at the opposite end of itsstroke, I provide the following mechanism: An operating-lever E ispivotally secured at e to one of the lay-swords a and has a pin-and-slotengagement at its lower end with the shaft ll. To its upper end ispivoted the upwardlycurved end 1l of a bar I, the body of which isintended to rest in proximity to the upper face of the vibratinglever G.An upwardlybent arm 'i' at the free end of the bar I has avertically-movable engagement in a bracket a3, fixed to the lay-sword aand serving as a guide for the free end of the said bar. A notch 112,formed in the under side of the bar I, is adapted to receive the freeend of the vibratinglever G when the said bar is allowed to drop at themoment the lever G is opposite the said notch. The bar I is heldnormally suspended by means of an arm h5, fixed to the shaft Il, whichextends under a projection h, extending laterally from an auxiliaryswinging arm hl, intermediate of the ends of the latter, the free end ofthe arm h7 forming a support for the bar I. From this it follows thatwhen the shaft Il is rocked by the dropping of the shuttle-boxes the armh5 will be rocked downwardly into the position as shown, for example, indotted lilies, Fig. 5, and if at this moment the vibrating lever G beopposite the notch 'i2 the latter will receive the said vibratingleverand the bar I will thereby be moved longitudinally, together with thelever G', and such movement of the bar I will, through the connection ofsaid bar with the shaft Il, move the shaft H in an opposite directionfrom that in which the bar I moves.

If therefore the vibrating lever G be at the opposite end of its strokefrom thc pocket hZ when the boxes fall, it will be engaged with the barl and the shaft II will be thereby moved in the same direction as itwould have been had the lever G engaged with the pocket h2 at theopposite end of its stroke. When the lever G is engaged in the pocketh2, the bar I will rest on the upper face' of the lever G. To preventthe bar I from dropping into position to engage the lever G as thelatter moves past the notch t2, I provide a guard hs, fixed to across-bar h4 and in position to receive a projection 3 on the back ofthe bar I and prevent it from dropping while the lever G is passing thenotch.

The three positions which the lever G and the bar I may assume withrespect to the shaft H and to each other are represented in detail inFigs. 4, 5, and G, the position in Fig.

4 being that in which the bar I is dropped into engagement with thevibrating lever G', and the latter being at the opposite end of itsstroke from the pocket h2 will ride on the periphery of the enlargedportion h of the shaft Il, the projection t3 on the bar I being broughtsufficiently low to pass underneath the guard hs. The posit-ion shown inFig. 5 is that in which the lever G is engaged with the pocket h2 in theshaft II, the bar I being now held upon the upper face of the lever Gand the projection 5. being in position to en; gage the upper side ofthe guard h8 when the lever G passes t-he notch in the bar I. Theposition shown in Fig. 6 is that in which the swivel-shuttle mechanismis out of action, the shaft ll being in the position which it assumesbefore the drop-boxes are let fall, the bar I being held supported bythe arms h5 and hl, as hereinbefore set forth.

From the above it follows that if the lever E occupy the positionrepresented in Fig. l it will be operated in a direction to throw itslower end to the left and its upper end to the right, no matter at whichend of the stroke of the vibrating lever G the drop-boxes be let fall,and if the said lever E were in the opposite position from that shown inFig. l, with its lower end to the left and its upper end to the right,it would be thrown in the opposite direction at the moment of the fallof the drop-boxes at either end of the stroke of the vibrating lever G.

The swivel-shuttles are represented by K K K2 K3. In the presentinstance I have shown a bank of four longitudinal series, the shuttlesin one of the longitudinal series being represented by K and those ineach of the other series by K K2 K3, respectively. They are operated bymeans of pinions 7c h', duc., engaged with rack-bars L L', dce., eachlongitudinal series being provided with its own independent rack-bar foroperating that series. Each of said rack-bars has its own independentuprising standard l l', dac., connected at its lower end with the bar,preferably by means of a bar-sprin g M M', dsc., the spring IOO IIO

being fixed at one end to the rack-bar and the standard being secured tothe free end of the spring, the tension of the spring tending at alltimes to holdthe standard depressed.

' Located within the swivel-shuttle beam and above the bank ofshuttle-driving rack-bars L L', &c.,are located a pair of lower rackbarsections N and N' and a pair of upper rackbar sections O and O. Theupper and lower sections N O and N' O' are spaced from each other andare adapted to engage the teeth on opposite sides of pinions P P',mounted upon axles secured tothe swivel-shuttle beam. The rack-sectionsN N' are connected by four bridge-pieces n n', dac., and the uppersections O O' are connected by four bridge-pieces, 0' 0', dac. The fourconnecting bridge-pieces of the upper and .lower rack-sections areintended to correspond to the four independent rackbars in engagementwith the four longitudinal series of swivel-shuttles. The standards ZZ', &c., connected with the independent rackbar sections, extendvupwardly through the swivel-shuttle beam in proximity to the edges ofthe bridge-pieces n' n', &c., and o' o', &c., and said standards `areprovided with projections Z4, extending laterally therefrom and adaptedto engage within notches or recesses 'n4 and 04, formed, respectively,inthe edges of the bridge-pieces of the lower and upper racksections. Thenotches niin the lower bridgepieces are covered by thin plates 'm5, sothat when the standards Z Z', dac., are elevated to bring the projectionZ4into one of the notches n4 in the lower bridge-pieces it will beprevented from passing on through said notch and will be held by saidplatein engagement with said lower bridge pieces. The lower bridgepiecesn' fn', dac., are narrowed at points n, (see Fig. 8,) so that when suchnarrowed portion is opposite one of the uprising standards Z theprojection Z4 on said standard will pass freely beyond the lowerbridge-piece and into engagement with the notch o4 in one of the upperbridge-pieces. Oneof the upper or lower rack-sections-in the presentinstance, the lower rack-section-N' is connected by an arm Q with thenotched loop R, fixed to the sliding bar r, engaged with the upper endof the lever E so that when the swivel-shuttles are dropped the saidlever will be connected with the lower racksection N', and will causeitto move in one direction or the other, according as the lever E is movedin one direction or the other. The longitudinal movement of therack-section N and the section N, connected thereto by the bridge-piecesn' n', &c., will cause a simultaneous movement of the upperrack-sections O O' in the opposite direction, because of theintermediate pinions P P', and hence any one of the independentrack-barsL L', &c.,vwhich shall at such time be connected by itsstandards Z Z', &c., with either the upper or lower rack-sections willbe caused to'move in the direction in which said sections are moving,and motion will thereby be imparted to the swivel-shuttles in anopposite direction thereto.

Whether one or more of the longitudinalv series of swivel-shuttles shallbe brought into operation at any one time may be determined by thepattern in the well-known Jacquard mechanism', not shown herein, butarranged to lift upwardly upon any one or more of the standardsZZ', asmay be desired. The connection of the Jacquard mechanism with thestandards Z Z', 85o., may be direct, and to this end the upper ends ofthe said standards are provided with perforations for the attachmentthereto of connecting-springs S. I prefer, however, to employ a parallelmotion-such, for example, as that shown in Fig.10, in which a horizontalfinger s is connected by a pair-of parallel bars s with a support s2,fixed to the beam, the upper bar 3' being provided with an eye s3 forthe attachment thereto of the spring S. The standards Z Z', dsc., areeach provided with a laterally-projecting pin s, (see Fig. 13,) adaptedto rest on the linger s, and thereby cause the standards to rise withthe lifting of the finger. The pin s4 is adapted to enter a verticalgroove S5, which communicates with a horizontal groove s, in which thepin s", when the standard is elevated to bring its projection intoengagement with the lower bridge-pieces n n', &c., rides throughout thelongitudinal movement of the rackbar, said groove S5 terminating in amouth at the top of the beam to allow the pin to ride along the top edgeof the beam when the said standard has been elevated to bring itsprojection intoengagement with the edge of the upper bridge-pieces o'o', dac. The variation in the amount of upward movement of the standardto engage the lower or upper bridge under the uniform lift by theJacquard mechanism is accounted for by the spring connections S.

If the shuttles in any one of the longitudinal series rest at theleft-hand ends of their strokes, their operating rack-bar will be at theright-hand end of its stroke. If at this time the lower rack-section bein the position indicated in Fig. l0, where the next stroke will be fromleft to right, the uprising standard Z' of the rack-bar to operate thatseries of sh-uttles will be in position, when lifted, to pass the lowerbridge-piece and engage with theupper bridge-piece, so that the movementof the lower rack-section to the right and the consequent movement ofthe upper rack-sections to the left will move said rack-bar having thestandards Z' to the left and the several shuttles of that series to theright vIl" at the s ame time the standard Z2 be lifted, it i will be 1nposition for its projection to en-` gage the notch in the lowerbridge-piece, andf,

it and its rack-bar connected therewith will be moved, together withsaid lower rack-sec-v tions, to the right, and the shuttles of that:series will be consequently moved to theleft. From this it follows thatat whichever end of 'L their stroke the shuttles of any series be left,
